The present invention relates to a bucket fitted to a vehicle intended to move, transport, tip a bulk material and spread it over a chosen thickness.
Spreading is defined as being spreading out a product or material over the ground, dispersing it.
The use of a spreading-out operation requires a special-purpose machine which is awkward to maneuver.
Another way of achieving spreading is to do it by hand using manual labor. In that case, the work still remains very difficult because the loads to be moved around are heavy and repetitive.
Document FR2779456 describes a grader blade fitted to a vehicle and intended for the handling of bulk materials. However, that device is not designed to adjust the thickness of the spreading.
Document U.S. Pat. No. 4,055,255 describes an industrial vehicle comprising a bucket. The bucket makes it possible to choose the quantity of bulk material to be tipped out, but the bucket disclosed is not in any way designed to regulate the thickness of the layer of material during the spreading phase.
The present invention seeks to overcome these disadvantages.
To that end, according to a first aspect, the present invention relates to a bucket for an industrial vehicle intended to load, move, transport, tip and spread a bulk material, the bucket comprises two lateral panels extending on each side of a loading panel, said loading panel comprises a loading edge and an unloading edge, notable in that the bucket also comprises:
Thanks to these measures, the bucket has several functions: loading, moving, transporting, tipping out a bulk material or spreading same over a chosen thickness.
Thus, the thickness of the bulk material tipped out during the spreading phase is kept fixed using a roller irrespective of the unevennesses of ground encountered.
The fixing attachment is a floating attachment and adapts to the terrain to ensure the same thickness of bulk material during spreading. The bucket is able to follow the contour of the route. The bucket perfectly follows the support and can be fitted to all types of loader (loading shovel, tractor shovel, telescopic loader, tractor loader, etc.).
The bucket makes it possible to:
Other advantages:
In one embodiment, the vertical travel of the fixing attachment is of the order of 0.5 to 50 cm, preferably from 1 to 15 cm.
In one embodiment, said roller is capable of vertical translational movement relative to the ground so as to vary the height of the bucket relative to the ground. Thus, the spreading thickness can be chosen.
In one embodiment, the gate is capable of rectilinear translational movement supported on guideways on each side of the gate, said mobility is actuated by actuating cylinders.
In one embodiment, the length of the roller is at least equal to half the length of the bucket.
In one embodiment, the bucket comprises a plurality of gates capable of rectilinear translational movement.
Thus, the bucket can tip a certain quantity of bulk material out on just one side or the other. In addition, the act of opening over a certain length makes it possible to vary the width of the strip of bulk material to be spread. Another advantage is, for example, that of opening a gate over a wheelbarrow and of being able to tip bulk material out to fill the wheelbarrow.
In one embodiment, it comprises a surface that reduces the opening created by the opening panel in the open position.
In one embodiment, the surface is capable of translational movement by means of an adjusting element that adjusts the position of the surface relative to the opening created by the opening panel in the open position.
The invention also relates to a vehicle equipped with a bucket described hereinabove.
Further advantages, objects and features of the present invention will become apparent from the following description given by way of entirely nonlimiting explanation with reference to the attached drawings in which:
The loading can be various types of material:
The bucket is used to load the bulk material from a heap. In another embodiment, the bucket is used to collect a bulk material under the dump gate of a truck.
In this case, the opening gate allows the bulk material to be released and to pour out.
More particularly,
The material leaves the bucket via the opening gate which releases the bulk material under the effect of gravity.
The loading panel 21 has four edges, two edges connecting the lateral panels 20, a loading edge 211 delimiting part of the main opening of the bucket, an unloading edge 212 delimiting part of a secondary opening. The unloading edge is on the other side of the panel from the loading edge 211. The secondary opening is controlled by the opening of the gate 24 on the opening panel 23.
The adjusting system 25 comprises two hand cranks (one on each side of the bucket), this is adjustable height-wise and thus makes it possible to choose the thickness E to be spread. The ground is depicted in dotted line and the difference between the bottom of the bucket and the ground is indicated by the reference E.
In one embodiment, the thickness differs from one side to the other.
The roller 27 has the advantage of having a bearing surface over the entire length of the bucket, thus avoiding under-thicknesses.
The fixing attachment 28 also has the ability to move about an axis of rotation 29 relative to the ground (arrow B). The axis of rotation is perpendicular to the support panel 22.
In an alternative form of embodiment, the mobile roller 27 is replaced by a caterpillar track system.
In one embodiment, the width of the bucket is 2 m. It is comprised between 1 and 3.5 m.
In another embodiment, the bucket comprises several opening gates making it possible to vary the spreading width.
In another embodiment, the opening gate comprises a guideway system to slide the gate from left to right, thus varying the spreading width.
The diameter of the roller is 20 cm. It is comprised between 10 and 50 cm.
In another alternative form which has not been depicted, the bucket comprises a plate positioned above the bucket leaving a width of opening that can be varied between 0.5 and 5 cm so that the chippings can be spread by inclining the bucket.
